Dell PowerEdge C6615
The Dell PowerEdge C6615 is a high-efficiency single-socket AMD EPYC modular compute sled designed for the 2U multi-node PowerEdge C6600 chassis. Leveraging AMD EPYC 9004 or 8004 Series processors, each C6615 node packs up to 128 cores, 6 DDR5 memory channels, and PCIe Gen5 expansion into a half-width sled. A fully populated 2U chassis delivers an astonishing 512 physical cores and 1024 threads with single-socket software licensing economics. The C6615 is engineered for hyper-scale cloud hosting, software-as-a-service, and digital render farms. Used buyers should inspect chassis backplane guide pins and node power delivery rails.

Works together
How the Dell PowerEdge C6615 connects to servers, storage and the network: 4 ways, with the parts and products on each path.
Fibre Channel SAN
Match the speed: 16Gb and 32Gb FC HBAs, switches and array ports work together, and each generation also runs one or two speeds below its own (a 32Gb port runs at 16Gb and 8Gb).

Optics
iSCSI and NVMe/TCP over Ethernet
Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.

Direct-attached SAS
12Gb SAS uses Mini-SAS HD (SFF-8644) connectors; older 6Gb gear uses Mini-SAS (SFF-8088). Adapter cables exist, but the link runs at the slower speed.

File storage (NFS and SMB)
Front-end ports face the clients; back-end ports (on scale-out systems) connect the nodes to each other and need their own switch pair.
